HennaTrace helps you trace henna designs using a live camera preview, built-in templates, and designs you choose to import.
HennaTrace does not sell your data, does not use your camera frames or photos for advertising or tracking, and does not upload your selected photos, imported designs, or camera preview frames to developer-controlled servers.
Camera preview, imported design processing, and tracing reference exports are handled on your device.
HennaTrace may handle the following information when you use related features:
HennaTrace is a creative tracing utility. It does not provide cloud backup, account services, identity verification, or medical advice.
Camera preview, image import processing, and tracing reference generation are performed on your device using iOS system frameworks.
Imported designs are saved locally in the app’s Application Support storage. HennaTrace does not operate a backend server for collecting your camera frames, photos, imported designs, or local app settings.
HennaTrace does not sell, rent, or share your camera frames, photos, imported designs, or local app settings with advertisers, data brokers, or third-party analytics services.
Subscription purchases and restores are processed by Apple StoreKit. Apple may handle purchase-related information according to Apple’s own terms and privacy policies.
If a future version adds optional account, backup, cloud sync, analytics, crash reporting, or third-party services, this policy will be updated before those features are used.
HennaTrace requests camera access to show the live tracing preview. Camera frames are used for the preview and for saving a tracing reference screenshot when you choose that action.
HennaTrace uses the iOS photo picker so you can choose an image to import. The app only receives the image you select through the system picker.
If you choose to save a tracing reference screenshot to Photos, HennaTrace requests add-only photo library permission. This permission is used only to write the screenshot. You can change camera and photo permissions at any time in iOS Settings:
After access is revoked, HennaTrace will no longer be able to use the related camera or photo feature unless you grant permission again.
Local app settings and imported designs remain on your device unless you delete them through available app or system controls, or uninstall the app.
Tracing reference screenshots that you save to Photos are managed by the Photos app and your iOS settings. Images or screenshots that you share outside the app are handled by the destination apps or services you choose.
HennaTrace is not directed to children. HennaTrace does not knowingly collect personal information from children through developer-controlled servers.
HennaTrace may be used by people in different countries or regions. The app is designed so camera and photo processing happens on the user’s device unless a future version clearly introduces optional cloud features.
This policy may be updated when HennaTrace changes how it handles data. The latest version will be published on this page with an updated date.
